To all whom it may concern:

Be it known that I, RAY P. JACKSON, a citizen of the United States, and a resident of lvilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Systems of,

divided by means of leads 5, 6, 7, 8 and 9- that are connected, respectively, to contact terminals 10, 11, 12, 13 and 14 of a switch device 15 and also to contact terminals 1(3, 17, 18, 19 and 20'with which a master switch arm 21 is adapted to engage. Switch arm 22 of the device 15 is operated by means'of a motor 23, which, as here shown, derives its energy from the transformer winding 2 and is employed to adjust of windings 24 and 25 of a voltage regulator which may be,

set.- forth in the subjecti'40,147, granted September 29, 1903, to the \Vestinghouse Electric & Manufacturing Company, as assigncc 0:13. G. Lamme, or it may be of any other suitable construction.

The voltage regulator may be employed to adjust the voltages supplied to any translating dev ce, such as a motor 26, and the circuits of the primary and secondary windings may be connected and arranged, with H.- S ect to the transformer winding '1, as set orth in the sill'ijei-t-i'nattcr of Patent No. 765,185, granted July 11'), 1904, to the Westinghousc Electric & llanul'zmtuiihg ("ompan as assignoc of 1%. (i. Lamina.

T in motor 2 may serve. to operate any suitable device or nic hanit-m, other than a voltage regulator, the movements of which the inductive relations in general construction, substantially like that matter of Patent No.

' the windings it is desired to govern accurately, a voltage regulator being shown merely for the purpose of illustrating a useful application of my invention.-

The circuits of the motor 23 are governed by means of a switch device 27. which, as here shown, comprises a walking-beam 2-8 having conducting sections 29 and 30 at its respective ends that are adapted to engage stationary contact teri'ninals 31 to 38, inclu-- sive, which areproperly connected with the terminals of the 'field magnet winding 59 and brushes 40 and 41. The walking-beam is normally maintained in a middle position by means of springs 42, and to it are attached magnetizable armatnres 43 and 44. for electroanagnets 45 and 46, -i.-espectively, that are provided, as shown, with windings 4T, 48, 49 and 50. .The windings 47 and 49 are connected in parallel between leads 8 and 9 from the transformer winding 2 and the windings 48 and 50 are connected in parallel between switch arms .21 and 22-.

In the drawing, the switch arms 21 and 22 are shown in engagement with the contact terminals 18 and 12, respectively, which are connected with the same point in the transformer winding the ott positions, under which conditions these being assumed asno difference of potential exists between the terminals of the windings bland 50. The windings 47 and 49 are energized continuously by reason of their permanent connection between leads 8 and E), but the walkingheam 28 is maintained in a middle position because the pulls exerted by the magnets 45 111N146 upon their respective armatures 43 and 44 are balanced.

If the switch arm 21 is moved into engagement with contact terminal 19', a voltage is impressed upon the windings 48 and 50 that is equal to the difference of potential between leads 7 and 8, and the resulting magnetic pull exerted by the winding 48 is added to that exerted by the winding 47, while the magnetizing forces exerted by 49 and 50 become opposed. The magnetic pulls exerted upon the armalnrcs 43 and 44 now no longer balance and the walking-beam is moved so as to bring conducting sections 29 and 30 into engagement with their corresponding contact terminals 31, 32, 37 and 38. The circuits are now so established that the motor 23 is caused to operate in a proper direction to ultimately bring the switch arm 22 into en-.

, motor circuits.

If the master switch arm 21 is moved into engagement with contact'terminal 17, the magnetizing forces of the windings 47 and 4S oppose each other, while the magnetizing forces of the windin s 49 and 50 supplement each other and tile resulting movement of the walking-beam 28 effects engagement of the conducting sections 29 and 30 with their corresponding contact terminals 33, 34,- 35 and 36. The circuits of the motor 23 are then so established as to cause rotation in the proper direction to bring the switch arm 22 into engagement with contact -terminal 11, the walking-beam 28 again returning to its central position after such engagement. If the master switch arm 21. is moved into engagement with contact terminal 16, the motor will continue in operation until switch arm 22 engages contact terminal 10, and if it is broughtinto engagement with contact terminal 20, the motor will rotate in the opposite direction until switch arm 22 is brought into engagement with accurately controlling the operation of the motor 23, the relative positions of the windings 24 and 25 of the voltage regulator may be altered at will and in accordance with the variations in position of the master switch arm 21.

l have illustrated two sets of the controlling devices that may be located on separate cars of a train and both may be controlled .by either of the master switch arms 21 and derive its energy from any suitable source the system may be further modified in many other than the transformer winding 2, and respects without departing from my invention.
